Security concerns about giving the apache user a tty

Question

I need to invoke sudo from a PHP script (web-triggered) so as to run a command as another user.
However, I get the message "sudo: sorry, you must have a tty to run sudo".

Would there be any security problem on giving the user nobody a tty??

Would you recommend a different approach to do what I need (run a shell script as a different user)?

Answer 1

Hmm sudo requires tty?

visudo

Disable an option for a user (or the default setting):
